An adolescent arrives at the emergency department (ED) with a fever and persistent lower right quadrant abdominal pain.
The patient is anxious, fearful, and hyperventilating.
What acid-base imbalance does the nurse anticipate the patient will develop?
Respiratory alkalosis.
Respiratory acidosis.
Metabolic alkalosis.
Metabolic acidosis.
The Correct Answer is A
Choice A rationale
Hyperventilation leads to a decrease in the amount of carbon dioxide (CO2) in the blood. This causes the pH of the blood to increase, resulting in respiratory alkalosis.
Choice B rationale
Respiratory acidosis is caused by a buildup of CO2 in the blood, typically due to hypoventilation (under-breathing). This is not consistent with the patient’s symptoms of hyperventilation.
Choice C rationale
Metabolic alkalosis is typically caused by a significant loss of acid from the body, such as from prolonged vomiting. This is not consistent with the patient’s symptoms.
Choice D rationale
Metabolic acidosis is typically caused by an increase in acid production within the body or a loss of bicarbonate from the body, such as in diabetic ketoacidosis or kidney disease. This is not consistent with the patient’s symptoms.

Correct Answer is C,A,B,D
Explanation
Step 1: Complete a focused assessment. The first step in managing a patient with abdominal pain and distention, vomiting, and constipation is to perform a focused assessment. This includes assessing the patient’s vital signs, pain level, abdominal distention, bowel sounds, and any other relevant physical findings.
Step 2: Elevate the head of the bed. Elevating the head of the bed can help reduce the risk of aspiration, especially in a patient who has recently vomited.
Step 3: Send the emesis sample to the lab. Analyzing the vomitus can provide important information about the possible causes of the patient’s symptoms. For example, the presence of blood could suggest a gastrointestinal bleed.
Step 4: Offer PRN pain medication. After the initial assessment and interventions, the nurse should address the patient’s comfort. Pain management is an important part of patient care, but in this scenario, it is not the highest priority.
Correct Answer is ["100"]
Explanation
Step 1: The child is receiving gentamicin 60 mg every 8 hours IV, which is to be infused over 30 minutes. The medication is delivered by the pharmacy diluted in a 50 ml bag of saline.
Step 2: We need to find the infusion pump’s regulation in mL/hour.
Step 3: Since the medication is to be infused over 30 minutes, we convert this to hours by dividing by 60. So, 30 minutes is 0.5 hours.
Step 4: The rate of infusion is then the total volume (50 mL) divided by the time in hours (0.5 hours).
Step 5: So, the infusion pump’s regulation is (50 mL ÷ 0.5 hours) = 100 mL/hour.
